Is an expensive robot vacuum worth it in 2026? The short answer: for most households, no — and the $400 price gap between the iRobot Roomba j9+ ($599.99) and the eufy RoboVac 11S MAX ($199.99) makes that gap impossible to ignore. The eufy holds a 4.4 adjusted rating across 45,000 reviews and a Mavrino Score of 9.5/10. The Roomba scores 4.2 adjusted across 3,500 reviews and a Mavrino Score of 7.3/10. The numbers don’t lie: the cheaper vacuum wins on almost every metric that matters to everyday users.
That said, the Roomba j9+ is not a bad vacuum — it’s a premium one, and premium makes sense in a specific scenario. If you have a large multi-room home, deep-pile carpet, and you genuinely want hands-free self-emptying so you can ignore the bin for weeks at a time, the extra spend has a real case. But if you’re a single-floor apartment dweller or a budget-conscious buyer who just wants clean floors without thinking too hard, the eufy 11S MAX is the smarter buy by a wide margin. This guide breaks down exactly where the Roomba earns its price — and where it doesn’t.

iRobot Roomba j9+ Self-Emptying Robot Vacuum
$599.99 ★ 4.2/5
The iRobot Roomba j9+ costs $599.99 and carries a 4.2 adjusted rating from 3,500 owners — a solid score, but the Mavrino Score of 7.3/10 reflects that the price-to-performance ratio is harder to justify against cheaper rivals. The standout feature is genuine: the self-emptying base means you can set it running and not touch the dustbin for weeks, which is a real quality-of-life upgrade for larger homes or allergy sufferers. Owners consistently praise its reliability and ease of daily use once set up, with 87% of reviews landing positive. The honest limitations are noise and a setup process that multiple owners found less intuitive than the price suggests — one 3-star reviewer explicitly noted it was ‘louder than expected.’ The Roomba j9+ is the right buy for hands-free households, not for budget-conscious ones.
👤 Best for: Larger homes, allergy sufferers, and anyone who wants a genuine set-and-forget experience with weeks between bin empties.

eufy RoboVac 11S MAX Robot Vacuum, Super-Thin, Strong Suction
$199.99 ★ 4.4/5
The eufy RoboVac 11S MAX at $199.99 is the strongest value robot vacuum in its class right now, and 45,000 owners back that up with a 4.4 adjusted rating and a Mavrino Score of 9.5/10 — the highest score in this comparison by a significant margin. Its super-thin profile lets it reach under furniture that taller vacuums miss entirely, and owners consistently praise how simple it is to live with day to day. The 87% positive review rate is meaningful precisely because it comes from a sample size large enough to trust. The trade-off is real: you have to empty the bin yourself, and the instructions get flagged as unclear by a portion of buyers. For anyone in an apartment or a single-story home who doesn’t want to spend $600, the eufy 11S MAX is the obvious, data-backed choice.
👤 Best for: Apartment dwellers, budget-conscious buyers, and anyone in a low-to-medium square footage home who wants reliable daily cleaning without the premium price tag.

The Verdict
The $400 price gap between these two vacuums is the verdict. The eufy RoboVac 11S MAX — rated 4.4 adjusted across 45,000 owners, Mavrino Score 9.5/10 — outperforms the Roomba j9+ on satisfaction, value, and ease of living with, for $199.99. For the overwhelming majority of US buyers in 2026, the expensive robot vacuum is not worth it. The eufy cleans your floors, fits under your furniture, and costs less than a third of the Roomba’s asking price. That’s a hard case to argue against.
The Roomba j9+ at $599.99 earns its place in exactly one scenario: you want self-emptying and you’re not willing to compromise on it. If you have a large home, pets, or allergies, and the thought of manually emptying a dustbin every couple of days genuinely frustrates you, the Roomba delivers a feature the eufy simply doesn’t have. That’s a legitimate reason to spend more — but it’s a narrow one. Know your own home before you spend the extra $400, because for most people, the eufy gives you 90% of the result at less than 35% of the cost.
Frequently Asked Questions
Is the iRobot Roomba j9+ actually worth $600 in 2026?
For most buyers, no. The eufy RoboVac 11S MAX scores higher (4.4 vs 4.2 adjusted rating, 9.5 vs 7.3 Mavrino Score) for $400 less. The Roomba’s self-emptying base is a genuine premium feature, but unless hands-free bin emptying is a priority, the extra spend isn’t justified by the cleaning results alone.
Does the eufy RoboVac 11S MAX work on carpet?
The 11S MAX handles low-to-medium pile carpet reliably — its strong suction is a praised feature across its 45,000-review base. It struggles on thick, high-pile carpet, where a more powerful vacuum like the Roomba j9+ has an edge. For hardwood floors and thin rugs, the eufy is excellent.
How often do you have to empty the eufy RoboVac 11S MAX bin?
Most owners empty it every one to three runs depending on home size and pet hair volume. It’s the main practical trade-off versus the Roomba j9+, which self-empties and can go weeks without manual intervention. If daily bin emptying sounds like a chore, the Roomba’s self-emptying base has a real argument.
Which robot vacuum is better for pet hair?
Both handle pet hair, but the Roomba j9+’s self-emptying base makes it meaningfully easier to manage in homes with heavy shedders — you’re not emptying a full bin after every single run. For light-to-moderate pet hair, the eufy 11S MAX’s strong suction is more than sufficient at less than a third of the price.
